Yorkshire (/ˈjɔːkʃə/) is a historic county of Northern England and the largest in the United Kingdom. Due to its great size in comparison to other English counties, functions have been increasingly undertaken over time by its subdivisions, which have also been subject to periodic reform. Throughout these changes, Yorkshire has continued to be recognised as a geographical territory and cultural region. The name is familiar and well understood across the United Kingdom and is in common use in the media and the military, and also features in the titles of current areas of civil administration, such as North Yorkshire, South Yorkshire, West Yorkshire and East Riding of Yorkshire. The county's name is commonly abbreviated as Yorks.

Within the borders of the historic county of Yorkshire are areas which are widely considered to be among the greenest in England, due to the vast stretches of unspoiled countryside in the Yorkshire Dales and North York Moors and to the open aspect of some of the major cities. Yorkshire has sometimes been nicknamed God's Own County. The emblem of Yorkshire is the white rose of the English royal House of York, and the most commonly used flag representative of Yorkshire is the White Rose on a dark blue background, which after years of use, was recognised by the Flag Institute on 29 July 2008.Yorkshire Day, held on 1 August, is a celebration of the general culture of Yorkshire, ranging from its history to its own dialect.

West Yorkshire is a metropolitan county within the Yorkshire and the Humber region of England with a population of 2.2 million. West Yorkshire came into existence as a metropolitan county in 1974 after the passage of the Local Government Act 1972.

West Yorkshire, which is landlocked, consists of five metropolitan boroughs (City of Bradford, Calderdale, Kirklees, City of Leeds and City of Wakefield) and shares borders with the counties of Derbyshire (to the south), Greater Manchester (to the south-west), Lancashire (to the north-west), North Yorkshire (to the north and east) and South Yorkshire (to the south-east).

West Yorkshire County Council was abolished in 1986, and so its districts (the metropolitan boroughs) are now effectively unitary authorities. However, the metropolitan county, which covers an area of 2,029 square kilometres (783 sq mi), continues to exist in law, and as a geographic frame of reference.

West Yorkshire encompasses the West Yorkshire Urban Area, which is the most built-up and biggest urban area within the historic county boundaries of Yorkshire.
